Agreed. Stay far, far away from K-Gut if you're looking for a string that's easy on the arm. It's VERY stiff for a multi. Even stiffer is K-Gut Pro. Run as fast and as far away as you can from K-Gut Pro if you want an arm-friendly string. I thought it was stiffer than some polys and it gave me tennis elbow very quickly even as just a cross with a soft multi main.
